It seems like a very basic function is missing from Whiteboards, and that is drag and drop animation support for videos and mp4's. Because my work requires an animation team to review my motion work, I have to use milanote, which is another version of Whiteboards to make this happen. Thus, I have to completely ignore Whiteboards, as its basically useless for me and other animators (or videographers) purposes.

Yes, I see that you do support embedding, but that adds lots of additional steps that could be avoided.

Doesn't it make sense to make drag and drop video a feature for mp4's?
